UNITED STATES 1,721,1 4 PATENT 'OFFlCE EiF JoHN o. NEWELL AND FRANKaEnrArH, or Melina stra t, oK'LAHoM FOLDING HAIR; p

This invention relates to folding chairs.

Objects of this invention are to provide a novel form of folding chairwhich is made primarily of angle iron and strap iron and which is soconstructed that it will fold flat in a very compact manner.

Further objects are to provide a folding chair which is formed in such amanner that it is practically indestructible, and is extremely rigid andwill stand an immense amount of abuse without deterioration.

Further objects are to provide a folding chair which may be very cheaplyproduced, which lends itself readily to quantity production, and whichis of pleasing and attractive appearance.

An embodiment of the invention is shown in the accompanying drawings inwhich:

Figure 1 is a sectional view through the chair corresponding to asection on the line 11 of Figure 2;

Figure 2 is a sectional view on the line 2-2 of Figure 1.

Referring to the drawings, it will be seen that the chair comprises apair of side bars 1 formed of angle iron. These side bars pivotallycarry angle irons 2 which support the seat. The seat is preferablyformed by means of a plurality of spaced slat-like members 8 secured tothe angle irons, and these slat-like members may, if desired, be formedof wood or metal.

Upholstery may be employed, if desired, although for outdoor use, theseat, as shown specifically in the drawings is preferred. It isintendedprimarily for tourists or outdoor use and will withstand the usualsevere strains.

The seat is provided with a transverse brace rod 4 adjacent its forwardportion which is securely attached, to the angle irons 2. Further, theangle irons 2 are provided with elongated slots 5 for a purposehereinafter to apear. p The side rails 1 are spaced apart at their upperends by means of a channel iron brace 6, and this brace is preferablyslightly curved, as indicated in Figure 1, so that it dips down in itscentral portion. The side rails 1 are further provided with an oflsetstrap iron brace piece 7 which acts as a stop for the seat when thechair is folded. This transverse member 7 or stop is set rearwardly ofthe outline of the side rail 1, as shown in Figure 1. The side rails arefurther joined adjacent their lower portions by means of a transversestrap Hon 8 which forms 1n effect a rung.

' The lower ends of the angle iron side rails have their outer flangesinturned as indicated means of a transverse portion 18, as shown inFigure 1.

In using the chair, it is extended as shown in Figure 1, and it will beseen that the chair is securely braced and furnishes a comfortablesupport for a seated person. When it is desired to fold the chair, allthat is necessary is to rock the seat upwardly, the seat being receivedbetween the siderails 1 and resting against the offset transverse stop 7In rocking the seat upwardly, the strap iron rear legslO rock forwardlyand pass between the side rails and contact with the stop 8. The seat isthus folded into a very compact formation, substantially flat, andoccupying a small amount of space.

Due to the peculiar manner in which the seat is formed, it is extremelyrigid and will withstand an immense amount of abuse withoutdeteriorating.

Although the invention has been described in considerable detail, suchdescription is intended as illustrative rather than limiting as theinvention may be variously embodied and as the scope of such inventionis to be determined as claimed.

We claim:

In a chair of the class described, a pair of side bars of angle ironoperatively disposed in an incline plane, a transverse strap ironconnecting the side bars at their lower ends, a channel iron braceconnecting the side bars at their upper ends, an offset strap braceattached to the side bars at a point between their centers and the upperends, a pair of parallel angle irons operatively disposed in ahorizontal plane and having their inner ends pivotally connected to theside bars upon their inner faces and having longitudinal slots at theirinner end portions, a transverse brace rod connecting the outer ends ofthe parallel angle irons, a plurality of slot-like members arranged uponand connected to the horizontally disposed portions of the parallelangle irons, strap iron brace members normally disposed in an inclineplane across the side bars and pivotally connected thereto intermediatetheir ends, a transverse portion con- Y necting the lower ends of thestrap iron brace members, and a transverse rod connecting the upper endsof the strap iron brace memhers With the ends of the rod movable in the1 slots in the parallel angle irons.

In testimony that We claim the foregoing We have hereunto set our handsat McAlester, in the county of Pittsburgh and State of Oklahoma.
